What are the best browsers for old PCs?

Opera One – Best browser for low-end PC

Opera One is perhaps the greatest browser to use on your old Windows PC running Windows 7 and later versions for fast page-loading speeds and advanced AI tools.

Useful features:

• Adblocker that loads webpages up to 90% faster
• Free VPN included
• Keyboard shortcuts instead of pointing and mouse clicking
• Tracker blocker that prevents data collection
• Intuitive and distraction-free browser experience

As older PCs are not as well-equipped to deal with demanding tasks as the newer versions, the way is built brings great advantages, as it is optimized to consume as few resources as possible.

One important aspect that enables Opera One to offer such great speeds is the fact that no ads are allowed, so the loading page times are reduced considerably.

Blocking ads means preventing unnecessary scripts from slowing you down, but you may also click Manage exceptions to whitelist those websites that shouldn’t be subject to ad-blocking.

We all know that computers running old operating systems are favorite targets for hackers. Even so, Opera One has got your back putting your data security and privacy first.

With a VPN built into the browser, you can ensure that your IP will not be tracked across the web, and at the same time will allow you to act region-restricted content without issues.

NOTE

Keep in mind that Opera One officially ended support for older Windows OS including XP and Vista. You may have to download older versions that aren’t as secure as the latest development.

Instead, it’s still a great browser that supports Windows 7 and Windows 10 and you can install it on your 5-year-old PC or more without any problems.

Which low-resource browsers are the fastest?

To answer this question, our team of testers has downloaded and installed all of the browsers we will cover in this article.

Each browser variant has been benchmarked using the Base Mark Web 3.0 test while using the same system, with the same configuration and number of running programs.

To understand the results, a higher score value implies better browsing speeds for the browsers presented below.

At the top of our list, we have UR Browser with a benchmark score of 1413.48, making it the fastest browser for all PCs and an excellent option for low-specced PCs worldwide.

Following close behind, we have Opera One with a score of 835.6, making it the second-fastest browser for PCs with low system resources.

Even though this browser was slower than UR Browser in our benchmark tests, it makes up tenfold by offering many unique features and customization options.

As you can see, two of the browsers could not be tested as the others. In the case of Midori, our testers have tried installing the browser on multiple devices.

Unfortunately, even though it installs, it doesn’t run at all, even with modified compatibility properties.

Regarding Lunascape Orion, even though the browser could be installed without issues, no benchmark tests could be run, as the Base Mark 3.0 test could not start.

Another essential factor to consider is your PC optimization, which can also increase the usability of all apps, including the browser.

What browser uses the least RAM?

Opera One takes the cake and has proven to have the least impact on your resources. If you’re wondering which browser is best for 1GB RAM, you’ll be pleased to know that it only uses around 600MB.

As we all know by now, not all browsers are built, work, or have the same capabilities, so understanding the intricacies of all these software options will allow you to make an informed decision.

One of the most impactful elements when it comes to using a browser on an older PC is the amount of CPU and RAM needed in order for the specific browser to run optimally.

The tests that we concluded were made using the same laptop while also playing the same youtube video at the same quality (720p).

Here are the results:

As you can see from the tests we performed, the browser which stands out with the most negligible impact on system resources is Opera One, using only 0.7 to 2.0% of the CPU and around 600MB.

This makes it the best browser for 1GB RAM PCs. It’s also the best browser for 2GB RAM PCs, for that matter.

In the same idea, this browser will also perform perfectly and offer you greater browsing speeds on a 4GB RAM system as well, making it the best browser for 4GB RAM laptops and PCs.

Close behind we have UR Browser that uses 0.8-2.0 % of the CPU’s power, and 650MB memory usage. This option could be fit to run on a 1GB RAM PC but loses in front of Opera One because of the security and stability differences.

The rest of the browsers, even if some are more lightweight than others, have shown varied results, so the decision might come down to the exact circumstances you find yourself in.

Taking the system usage data for each of these browsers and combining this information with the results of the benchmark tests, we can come to a set of very specific conclusions:

How can I improve my computer’s performance?

The exact answer to this question will depend on what operating system you have installed at the moment, but we will try to answer it in a more general manner.

➡ Clean up any software you don’t use

You can perform this action either by using specialized uninstaller software or by following the steps mentioned below to do it manually.

It is worth noting that these steps are for Windows 10, but they apply to most OSs.

1. Click Start and open the Control Panel by searching for it.
2. Choose Programs and Features from the list of options.
3. Scroll through the programs list and identify the ones that you don’t need.
4. Click on each of them and choose Uninstall.
5. Follow the on-screen instructions to complete the process.

➡ Optimize your HDD

Optimizing your HDD will most certainly improve your PC’s speed, but don’t expect wonders to happen if the hardware capabilities are very limited.

By performing this step, an improvement of 3-4% is possible, with the rate increasing exponentially if your hardware is more capable.

➡ Upgrade your PC’s hardware

Even though this might seem like an obvious step, upgrading your PC with new components will play the biggest role when trying to optimize your PC’s speed.

A few elements you need to consider here include the following:

• Your PC’s motherboard capabilities

In case your PC is very outdated, then it will imply that the motherboard installed on your PC will not be capable of handling any new hardware, or, that it will only allow for a slight improvement.

Because the motherboard is the base on which your PC components interact and work, having a capable one makes a huge difference, both in terms of short-term and long-term usability.

If you find that your PC’s motherboard is not updated enough to help you build your PC for greater speeds, then the safest bet is to invest in a motherboard that allows for greater improvements.

In case your motherboard is capable enough, then following the next steps will prove helpful.

• Hardware compatibility

If now you have a newer version motherboard or if you found that it allows worthy improvements, then the next thing to consider is the new hardware compatibility with your PC’s base.

In the same way, not all motherboards are built the same, other computer hardware is the same. Some GPUs might work with your motherboard, and some won’t.

For this reason, it is recommended that before investing in a good CPU, you make sure that your motherboard can use it.

The same principles apply if you decide to invest in a GPU, Rapid Access Memory (RAM), or even HDD.

• Cost of improvements

When planning to upgrade your PC, and moved on from the first two elements mentioned above, you will need to consider what the overall cost of this improvement will be.

Are the improvements it will bring to the table worth it? If not, you might consider saving some money and investing later on in a new PC altogether.

In most cases, it is better to buy a new system and gradually build upon it, than to try and rebuild an outdated PC from scratch.

How do I update my browser on an old computer?

Assuming that your old computer is still running well enough to open and run the version of Windows it has installed, the answer to this question will come down to what browser you’re using.

As you might expect, we can not cover the exact steps for each of the browsers available on the market, but here are some useful tips to use in case your browser can not be found in the list above:

• Verify the Help, Settings, and About sections inside your browser. The update option is usually located here.
• If none of these options are available, check for the Update or Upgrade options inside the main menu.
• If none of the above-mentioned options are available, visit the official browser webpage for more information on this topic.

What are some old browsers that still work?

No matter if it’s out of curiosity and nostalgia, or if you simply want to use an older version of the browser on your system, here are some of the oldest browsers that still work:

• AOL Explorer
• Flock
• GreenBrowser
• Internet Explorer
• K-Meleon
• Maxthon
• Netscape Navigator

As you can see, not all of these options are included in our main list, as we made sure to choose the best options available.

Best browser for Windows XP

Tip

It is not safe to use the Windows XP operating system, as it hasn’t received any security patches since April 2014. Please make sure to upgrade your OS to a newer version of Windows as soon as possible.

Choosing the right browser for an operating system as old as Windows XP can be a tricky task, as most software developers have moved on from creating software that is compatible with this OS.

Using the built-in Internet Explorer browser should be avoided at all costs, as it can become a major security breach.

Added to that, in order to run other browsers on Windows XP, you will have two main options to choose from:

• Slimjet version 10
• Vivaldi version 1.0
• Firefox 43.0.1 for 32-bit XP
• Firefox 43.0.1 for 64-bit XP
• Mypal Browser
• K-Meleon 75

It would be recommended that you try both options and choose the one that fits your needs best.

Best browser for Windows Vista

Having a good browser for Windows Vista will impact your online experience tremendously, no matter what OS you are using.

This principle applies even more when talking about older OS versions, as compatibility and even security issues may arise as a result.

• Firefox 52.9 ESR
• Internet Explorer 9
• Google Chrome 49
